Motor vehicle exhaust arc arrester test device

Abstract

The invention discloses a motor vehicle exhaust arc arrester test device which comprises a fan, a delivery pipe, an exhaust pipe silencer, intelligent flow totalizers, orifice plate flowmeters, a differential pressure gauge, a coal supply mechanism and an active carbon granule colleting device. The motor vehicle exhaust arc arrester test device is characterized in that two delivery pipelines are arranged between the exhaust pipe silencer and the active carbon granule colleting device, the orifice plate flowmeters and the intelligent flow totalizers are arranged on the two delivery pipelines, and the coal supply mechanism is adjustable and with a constant speed. The motor vehicle exhaust arc arrester test device has the advantages that the coal supply mechanism with the constant speed is adopted, the orifice plate flowmeters and the intelligent flowmeters are adopted, wherein the orifice plate flowmeters and the intelligent flowmeters are with two sizes, so that accuracy of test results is improved greatly. The motor vehicle exhaust arc arrester test device is simple in structure, high in measuring accuracy, wide in measuring range, stable in measuring and convenient to maintain.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for a spark extinguisher in an exhaust pipe of a motor vehicle. Background technique [0002] Existing motor vehicle exhaust spark arrester tests are carried out according to the engine displacement and rated speed of the vehicle and the air flow in the delivery pipe through the regulating valve. Since the air flow provided by vehicles with different displacements is different, the It is troublesome to adjust, the detection speed is slow, and it also affects the accuracy of data processing. [0003] At present, because the sales of four-wheel vehicles are mainly in the United States, all four-wheel vehicles sold to the United States must meet the requirements of the American National Standard ANSI SVIA-1-2007 "Four-Wheel All-Terrain Vehicle". The standard requires all all-terrain vehicles to be equipped with spark arrestors. And it is required that the performance of the spark arr...
